| Research Abstract |
In this study, beautifulness of geometrical figures is focused on and the following five viewpoints are identified so that students can appreciate the beautifulness of geometrical figures.
(1) Visual beauty of geometrical figures
(2) Beauty of geometrical figures having a common property in a general case
(3) Beauty of geometrical figures to be applicable into a society
(4) Beauty of unanticipated ideas when manipulating geometrical figures
(5) Beauty to be explained by using concrete geometrical figures
Through experimental classroom teaching at elementary, junior and senior high school, the case based basic framework of teaching flow so that students can appreciate the beautifulness of geometrical figures is clarified as follows.
(a) Letting students be trouble with manipulating geometrical figures
(b) Finding something concerning with beautifulness of geometrical figures
(c) Looking back and appreciating the beautifulness of geometrical figures
